Data structure preset

[chiaweh2]

Should we just preset the data structure which will be

1. easier for the user to follow instead of setting up the data structure themselves
2. make the io module easier to setup
3. the "empty" data structure can be controlled by the developer in case of future expansion but may cause conflict if user put files in the

maybe a separate repo just for the data structure will be beneficial instead of setting up in the same repo?

A feature-datastructure branch is in dev for this very purpose. The idea is to setup data class objects for all available options and also for setting up the correct path and filename. Some benefits from this

• [ ] centralized control on the filename and data structure
• [ ] automatically create the correct cefi data structure
• [ ] generate valid data path
• [ ] generate valid filename
• [ ] possible filename check
• [ ] possible data path check
• [ ] batch renaming
• [ ] check existing files in a specific set of experiment
